Golf training device

ABSTRACT

A golf training device having a circular track loop along which a golf club is swung and which is adjustable in height and angle to a trainee and his club. The loop is supported on vertically adjustable stanchions provided at the ends of a semicircular base member. Diametrically opposed stop collars on the loop are pivotally secured to the upper ends of the stanchions. Slotted adjustable plates are bolted to the stanchions and pivotally secured to the loop.

ATENTED JUN 8 I971 3583707 MI CHI NOR]. FUJI MO'lO INVENTOR am mJ/M ATTORNEY sour TRAINING nsvrcs BACKGROUND OF THE INVENTION This invention relates to a golf training device for training a person to develop the proper motion for a sound golf swing.

In these days, the number of golf players has increased remarkably, however, almost all beginners are said to lay more stress on the theory than the technique of golf and accordingly show slow progress. Beginners often develop the habit of swinging recklessly, thereby playing poorly. However, if a proper swing is developed, it is possible to improve play and thus obtain more enjoyment from the game. In prior golf training devices it has been possible to indicate deviation of a club head in the upper and lower sides and the right and left sides just when the club came in contact with the ball. However, there has been no device for permitting a track freely traced by the club head to be set up so as to practice a correct swing by making use of this track.

The present invention is characterized by erecting extensional stanchions near both ends of a semicircular ballast base, pivoting on the ends of said stanchions a track loop, providing a means adapted to permit the height of said stanchions to coincide with the height of the shoulder of a golfer standing at the middle between said stanchions, and providing a means for selectively adjusting said track loop on both stanchions so as to allow the angle between the club and the body of the golfer at the moment the club strikes a ball to coincide with the angle between said stanchions and said track loop, and thereby allow the club head to swing along said track loop. Therefore, an object of the present invention is to provide a golf training device which has a track to be traced by the club head and which is thereby serviceable to practice swings repeatedly so as to develop a proper swing in order to make rapid progress without receiving special coaching by a professional golfer.

Another object of the present invention is to provide a golf training device which is very simple in construction, and accordingly easy to manufacture, easy to handle, and low in pnce.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a preferred embodiment in accordance with the present invention.

FIG. 2 is an enlarged side view of the a portion of the embodiment shown in FIG. 1.

FIG. 3 is a perspective view illustrating the use of the preferred embodiment in accordance with the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT In FIG. 1 showing a preferred embodiment in accordance with the present invention, near both ends of semicircular ballast base 1 made of metal material having a diameter from 2.8 to 3 meters there are provided integral hollow square stanchion supports 2a, 2b so as to support therein first square stanchions 3a, 3b having slidably positioned therein second square stanchions 4a, 4b provided with holes a, 10b. Track loop 5 made of metal material having a diameter from 2.8 to 3 meters is pivoted by means of stop collars 6a, 6b on the ends of second square stanchions 4a, 4b. Slotted link plates 70, 7b are pivotally connected to track loop 5 and have the slots thereof fitted over bolts integral with second square stanchions 4a, 4b so as to adjust freely the angle between said track loop 5 and said second square stanchions 4a, 4b.

Referring also to FIG. 2, second stanchions 4a, 4b are fixed within first square stanchions 3a, 3b by means of check pins 9a, 9b inserted into holes I0a, 10b after suitably adjusting the height. After adjusting the angle between track loop 5 and the stanchions, track loop 5 is fixed to second square stanchions 4a, 4b by suitable means such as wing nuts 8a, 8b.

In making use of this embodiment of the present invention, as shown in FIG. 3 a trainee 11 will stand at the middle of line 15 connectings uare stanchions 3a, 4a and square stanchions 3b, 4b. The heig t of square stanchions 4a, 4b is then adjusted by extension out of square stanchions 3a, 3b and fixed by means of check pin 9a, 9b so as to allow the height of stop collars 6a, 6b on track loop 5 to coincide with the height of the trainees shoulder. The trainee will then assume his usual stance in addressing the ball 13 on mat 14 with club 12. The angle between track loop 5 and square stanchions 3a, 3b, 4a, 4b is then adjusted by means of slotted link plates 7a, 7b and fixed by means of wing nuts 84, 8b so as to coincide with the angle between the trainees body and the line from his shoulder to ball 13 through his hand and club 12. A path traced along track loop 5 by a club swung in this manner is the path of the club when a proper swing is practiced. Therefore, when the trainee practices his golf swing along said track loop 5 he can duplicate the proper swing so as to acquire skill in the game. According to the present invention, it is possible to conveniently set up the path of swings in conformity to all woods and irons. In practice, if resistance is felt between the club and the track loop, it indicates to the trainee that something wrong must be corrected is in his stance in addressing the ball, or holding the club, or any other motion. And thus, when the swing is practiced repeatedly, skill in this fundamental motion is acquired such that the golfer may eventually swing the club in the proper manner without making use of the track loop, and it is possible to make very rapid progress.

It is apparent from the foregoing description that the golf training device in accordance with the present invention can be manufactured at a relatively low price and be very serviceable for all golfers to improve the technique of their golf play. And in addition, this device is simple in construction and easy in handling, whereby one is able to practice swings scientifically without receiving special coaching by a professional golfer.

While one embodiment of the present invention has been illustrated and described in detail it will be understood that variations and changes may be made therein without departing from the invention as set forth in the appended claim.
